Clicking on Group tabs not working except the first

[smart]

Hello Sir,

I got a strange issue now.
Only the first tab is shown. Clicking on other tabs is not working at all.
I have installed a few templates prior to that. but not changing to any template.
It happened on all the tabs of other forms too.
Any idea how to troubleshoot.
Thanks

Frontend: Use original Protostar Joomla template and original Fabrik bootstrap_tabs template, is this working?
Is it working in the backend (bootstrap_tabs selected as form's Admin template, is this working?

Check your browser console for JS errors.

Thank you Troester.
Both templates are not working. But I found the issues.
When those templates were installed, there were some plugins are installed together.
One of those was giving that issue and when it was switched off, everything is back to normal.
It might be a bug or something.
Thanks anyway.
